Rose plant named ‘POULcs007’

ABSTRACT

A new garden rose plant of the floribunda class which has abundant, pink flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical classification: Rosa hybrida.

Variety denomination: ‘POULcs007’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between an unnamed female parent plant, and a male parent named ‘POULskov’, described and illustrated in U.S. Plant Pat. No. 9,062 dated Feb. 28, 1995. The two parents were crossed during the summer of 1992 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULcs007’.

The new variety may be distinguished from its unnamed female seed parent, by the following combination of characteristics:

1. While the seed parent has apricot flowers. ‘POULcs007’ has pink flowers.

2. While the seed parent has 50 to 60 petals. ‘POULcs007’ has 75 to 80 petals.

The new variety may be distinguished from its male pollen parent, ‘POULskov’ by the following combination of characteristics:

1. While the pollen parent ‘POULskov’ has a general tonality of Red Group 49D to Red Group 56D, the same of ‘POULcs007’ is Red Group 49B.

2. ‘POULcs007’ develops flower buds in cymes of seven flower buds per stem. ‘POULskov’ exhibits fewer than seven flowers per stem.

The objective of the hybridization of this rose variety was to create a new and distinct variety for garden use with unique qualities, such as:

1. Uniform and abundant orange-red flowers;

2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;

3. Disease resistance;

4. Continuous flowering;

5. Suitability for growing in a container.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘POULcs007’ from all other varieties of which we are aware.

As part of their rose development program, L. Pernille Olesen and Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter of 1992 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULcs007’ was selected in the spring 1993 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULcs007’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in July, 1993. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULcs007’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULcs007’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 3 years of age, grown on Rosa multiflora understock. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 1995, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety ‘POULmax’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. application Ser. No. 10/192,746 dated Jul. 9, 2002 are compared to ‘POULcs007’ in Chart 1.
